Aren’t there any better-known names for Phillips screwdrivers?
People may be assuming they’re more special than they are. In Denmark, they’re ubiquitous and just known as “star screwdrivers”.
My phone has bright spots too, I figured I must’ve pushed on it too hard at some point. When I got my Fairphone, I got a lot of random reboots, but they got significantly rarer with each software update, so I recommend to everyone to keep their phone updated and not assume it’s a hardware problem (whether it’s caused by Android or Fairphone, I don’t know).
As to why people get anxiety about disassembling it, I suspect it’s much like what teachers experience every day. When you don’t think you can learn something, you refuse to try, because trying requires effort. Also, I suspect people don’t want to think of themselves as electronics nerds. I was like that once, so I avoided learning about computers because I was ashamed of being interested in them.
The bright spots’ cause is not known yet. I don’t think it’s caused by user-induced-pressure, but what’s definite: Disassembling does not influence the bright spots either way.
